ABSTRACT:
An expansible chamber device in which a cylinder of preferably rectangular configuration supports a pair of opposing flaps pivotally attached to the corners of the cylinder. The flaps sealably and slidably engage the top surface of a piston disposed within the cylinder such that the surface area of the flaps together with the exposed surface area of the top surface of the piston between the flaps constitutes the effective working area of the device. This area is considerably greater than the area of the piston surface itself whereby overall efficiency of the chamber is increased.
